If you’ve ever driven down Interstate 295 through Johnston, you know the smell. It’s heavy. It’s distinct. That massive hill looming over the highway isn’t a natural part of the New England landscape; it’s the Central Landfill, the literal heart of Rhode Island Resource Recovery. It’s where almost everything we throw away in this tiny state ends up. But there's a problem. We’re running out of room.
It’s getting tight.
Most people think of "the dump" as a static hole in the ground where trash just sits. That’s not it at all. Rhode Island Resource Recovery (RIRRC) is actually a massive, quasi-public agency managing a high-tech engineering marvel that manages roughly 750,000 to 1 million tons of waste every single year. It’s a balancing act of chemistry, heavy machinery, and constant regulatory pressure from the EPA and RIDEM.
The 2040 Problem: Why the Central Landfill is Screaming for Space
Here’s the reality. The Central Landfill is currently projected to reach its capacity by roughly 2040. That sounds like a long time away, right? It isn't. In the world of municipal planning and environmental engineering, fifteen years is basically next week.
When that hill is full, it's full. You can't just "add a floor" to a landfill indefinitely without risking a catastrophic slope failure or massive environmental leaks. RIRRC has been working on "Phase VI" of the landfill for years, which involves lining new sections with high-density polyethylene and crushed stone to catch "leachate"—that nasty, toxic soup that forms when rainwater filters through garbage.
If we hit 2040 and the landfill is at its physical limit, Rhode Island faces a massive financial crisis. Right now, because we own our own landfill, tipping fees (the price towns pay to drop off trash) are relatively low compared to our neighbors in Massachusetts or Connecticut. If we have to start trucking our trash to Ohio or Pennsylvania? Your property taxes are going to skyrocket. Honestly, it's that simple.

What’s actually in the hill?
It’s not just banana peels and old sneakers. The waste stream at the Central Landfill is a mix of:
- Municipal Solid Waste (MSW): This is your kitchen trash.
- Construction and Demolition (C&D) Debris: Drywall, wood, and shingles from that renovation down the street.
- Commercial Waste: Stuff from big-box stores and restaurants.
- Sludge: Treated remnants from wastewater plants.
The Materials Recycling Facility (MRF) and the "Wish-cycling" Nightmare
Right next to the big hill is a building that smells slightly better: the MRF. This is where your blue bins go. Rhode Island uses a "Single Stream" system, which is great for convenience but kind of a disaster for purity.
People love to "wish-cycle." You know the feeling. You have a greasy pizza box or a plastic toy that feels like it should be recyclable, so you toss it in the blue bin because you want to do the right thing.
Stop doing that.
When you put a "tangler" (like a garden hose or Christmas lights) into your recycling, it winds around the giant spinning discs at the RIRRC facility. They have to shut down the entire multi-million dollar line just so a guy with a utility knife can crawl in there and cut your old hose out of the gears. It’s dangerous and it’s expensive.

Contamination is the biggest enemy of Rhode Island Resource Recovery. If a load of paper is soaked in soda or mixed with shards of broken window glass (which isn't the same as bottle glass!), the whole bale might become unmarketable. We sell our recyclables on the global commodities market. If the quality is low, nobody buys it, and it ends up—you guessed it—back in the landfill.
Gas Recovery: Turning Rot into Power
One of the cooler things happening in Johnston that nobody talks about is the gas. As organic matter breaks down inside the Central Landfill, it produces methane. Methane is a potent greenhouse gas, but it's also fuel.
RIRRC works with Broadrock Renewables to capture this gas through a massive network of underground pipes. They vacuum the gas out of the landfill and pipe it to a power plant that generates enough electricity to power about 28,000 homes. It’s a clever way to turn a liability into an asset. Without those wells, the smell in Johnston would be ten times worse, and the environmental impact would be staggering.
Why "Biodegradable" is Often a Lie
Let’s get nerdy for a second. Landfills are specifically designed not to break things down quickly. They are "dry tombs." To prevent groundwater contamination, the trash is compacted tightly and covered with dirt every single night to keep oxygen out and pests away.
Without oxygen, even "biodegradable" stuff doesn't rot properly. There have been excavations of old landfills where researchers found newspapers from the 1950s that were still perfectly readable. If you throw a "compostable" plastic cup into the Central Landfill, it’s going to stay there for decades. It needs a high-heat industrial composting facility to actually break down, and Rhode Island’s current infrastructure for that is still in its infancy.

The Economic Reality of Trash in the Ocean State
RIRRC doesn't just run on good vibes; it's a business. They rely on tipping fees. When the economy is booming, people buy more stuff, throw more stuff away, and construction spikes. That means more money for the agency but a faster-filling landfill.
When the economy slows down, the "trash volume" drops. It’s a weird economic indicator.
There’s also the "Out-of-State" drama. For years, there have been battles about whether the Central Landfill should take trash from outside Rhode Island. The logic is simple: more trash from Massachusetts means more immediate cash, but it eats up our precious remaining space faster. Currently, the focus is strictly on Rhode Island’s needs, but as the 2040 deadline approaches, the pressure to find new revenue streams or alternative disposal methods will get intense.
Common Misconceptions About Rhode Island Resource Recovery
- "They just throw the recycling in the trash anyway." Not true. It would be a massive waste of money for them to do that. They make money selling the sorted bales of plastic and aluminum. They only landfill recycling if it’s so contaminated that it’s literally garbage.
- "The landfill is leaking into the water." The older sections of the landfill (from the 70s and early 80s) didn't have the advanced liners we use today. However, RIRRC spends millions on a massive "pump and treat" system to contain the legacy plumes and protect the Scituate Reservoir nearby.
- "Plastic bags are fine in the blue bin." No. Never. They are the #1 cause of machinery jams. Bring them back to the grocery store or throw them in the trash.
Actionable Steps: How to Actually Help
If you live in Rhode Island, you are a shareholder in this landfill. Its lifespan directly affects your wallet. Here is what you actually need to do to keep the Central Landfill open as long as possible:
- Check the "A to Z" List: RIRRC has an incredible database on their website. If you don't know if an old microwave or a gallon of paint can go to Johnston, look it up. Don't guess.
- Scrub your jars: A peanut butter jar with a quarter-inch of gunk in the bottom can ruin a whole batch of plastic. A quick rinse makes a huge difference.
- Grass cycling: Stop bagging your grass clippings. Leave them on the lawn. They don't belong in a landfill, and they are basically free fertilizer.
- Eco-Depot for Hazards: Don't pour chemicals down the drain or toss them in the trash. RIRRC runs "Eco-Depot" days where you can drop off household hazardous waste for free. Use them.
- Small stuff matters: The 2040 deadline is a collective problem. If every Rhode Islander reduced their trash output by just 10%, we could push that closure date back by years.
The hill in Johnston is a monument to our consumption. It’s easy to ignore when it’s just a shape on the horizon, but the engineering and the stakes involved are massive. We have one shot to manage our waste correctly before we start paying the literal price of shipping our problems elsewhere.
